Prank Caller Destroys MSNBC’s ‘The Cycle’

'You're a dumbass, aren't you?'

A supposed “witness” to the crash of a Malaysian airliner in Ukraine told MSNBC’s Krystal Ball Thursday that it appeared to have been shot down by a “blast of wind from Howard Stern’s ass.”

He then called her a “dumbass” when she didn’t seem to understand she was being punked.

Ball appeared to either not hear him or understand the joke about Stern, immediately asking the “sergeant” about his military training and what sort of missile system he thought had taken down the plane.

“Boy, you’re a dumbass, aren’t you?” the caller said.

Ball replied, “I’m sorry, sir?” When the line went dead, The Cycle went to a quick break.

Ball said afterwards it was clearly “not actually an eyewitness” on the phone.
